ST has announced the STM32Trust to guide designers’ efforts to build strong cyber-protection into new the IoT devices leveraging industry best-practices.
STM32Trust combines knowledge, design tools, and ready-to-use original ST software. These help designers take advantage of features built into STM32 microcontrollers to ensure trust among devices, prevent unauthorized access, and resist side-channel attacks. All this averts data theft and code modification.
Ricardo De Sa Earp, General Manager of STMicroelectronics’ Microcontroller Division, commented, “STM32Trust eases developers’ understanding and acceptance of the new mandatory security rules, which is a key emerging challenge in the general-purpose microcontroller market today.”
Integrating all available cyber-protection resources for the STM32 family, STM32Trust helps designers implement a robust multi-level strategy leveraging security-focused chip features and software packages.
STM32Trust provides product developers with all they need to protect connected objects effectively using these features, including reference material and free software.
Among the reference software packages, X-CUBE-SBSFU demonstrates how to protect application code at its most vulnerable when being transferred into boot memory or updated in the field. X-CUBE-SBSFU reference packages are available for the STM32F4, F7, H7, L0, L1, L4, G0, G4, and WB. There is also a reference implementation of ST’s secure element STSAFE, which maximizes the security level of the final application.
In addition, Secure Firmware Installation solutions for STM32L4 and STM32H7 microcontrollers provide protection while devices are being programmed for the first time. The solution offers a complete toolset to encrypt OEM binaries with the Trusted Package Creator software, the STM32CUBEProgrammer to flash securely the STM32, and the STM32HSM to transfer OEM credentials to the programming partner.
